The text of a C++ program consists of tokens and white space. A token is the smallest element of a C++ program that is meaningful to the compiler. The C++ parser recognizes these kinds of tokens:

I'm involved into the development of Open IV, this is the biggest and the greatest project we ever did. For the system software development I prefer to use that programming language which is more suitable for the task, so most of my code is written on C/C and Delphi. Apr 14, 2010 sudo grep -a -Bnumber of rows before the text being searched -Anumber of rows after the text being searched 'some unique text in the lost file' /dev/sda3 test.cpp After a few minutes, a log file and a.cpp file were generated where I found my code by entering the command 'vim test.cpp'. Fortunately, Webopedia's Complete List of Data File Formats and File Extensions makes it quick and easy to sift through thousands of file extensions and data file formats to find exactly what you need. You can peruse the full list or search for data formats and file extensions based on. Jul 16, 2009 Bloodshed Dev-C is a free C compiler and development environment for Windows operating systems. Like most C compilers, it also can be used to compile ANSI C. By installing the GLUT header and library files, it can be used to write programs that use OpenGL.

Tokens are usually separated by white space, which can be one or more:

  • Blanks
  • Horizontal or vertical tabs
  • New lines
  • Form feeds
  • Comments

Basic source character set

The C++ standard specifies a basic source character set that may be used in source files. To represent characters outside of this set, additional characters can be specified by using a universal character name. The MSVC implementation allows additional characters. The basic source character set consists of 96 characters that may be used in source files. This set includes the space character, horizontal tab, vertical tab, form feed and new-line control characters, and this set of graphical characters:


a b c d e f g h i j k l m n o p q r s t u v w x y z


0 1 2 3 4 5 6 7 8 9

_ { } [ ] # ( ) < > % : ; . ? * + - / ^ & ~ ! = , ' '

Microsoft Specific

MSVC includes the $ character as a member of the basic source character set. MSVC also allows an additional set of characters to be used in source files, based on the file encoding. By default, Visual Studio stores source files by using the default codepage. When source files are saved by using a locale-specific codepage or a Unicode codepage, MSVC allows you to use any of the characters of that code page in your source code, except for the control codes not explicitly allowed in the basic source character set. For example, you can put Japanese characters in comments, identifiers, or string literals if you save the file using a Japanese codepage. MSVC does not allow character sequences that cannot be translated into valid multibyte characters or Unicode code points. Depending on compiler options, not all allowed characters may appear in identifiers. For more information, see Identifiers.

END Microsoft Specific

Universal character names

Because C++ programs can use many more characters than the ones specified in the basic source character set, you can specify these characters in a portable way by using universal character names. A universal character name consists of a sequence of characters that represent a Unicode code point. These take two forms. Use UNNNNNNNN to represent a Unicode code point of the form U+NNNNNNNN, where NNNNNNNN is the eight-digit hexadecimal code point number. Use four-digit uNNNN to represent a Unicode code point of the form U+0000NNNN.

Universal character names can be used in identifiers and in string and character literals. A universal character name cannot be used to represent a surrogate code point in the range 0xD800-0xDFFF. Instead, use the desired code point; the compiler automatically generates any required surrogates. Additional restrictions apply to the universal character names that can be used in identifiers. For more information, see Identifiers and String and Character Literals.

Microsoft Specific

The Microsoft C++ compiler treats a character in universal character name form and literal form interchangeably. For example, you can declare an identifier using universal character name form, and use it in literal form:

The format of extended characters on the Windows clipboard is specific to application locale settings. Cutting and pasting these characters into your code from another application may introduce unexpected character encodings. This can result in parsing errors with no visible cause in your code. We recommend that you set your source file encoding to a Unicode codepage before pasting extended characters. We also recommend that you use an IME or the Character Map app to generate extended characters.

END Microsoft Specific

Execution character sets

The execution character sets represent the characters and strings that can appear in a compiled program. These character sets consist of all the characters permitted in a source file, and also the control characters that represent alert, backspace, carriage return, and the null character. The execution character set has a locale-specific representation.

How to Install Dev-C++ and the GLUT Libraries
for Compiling OpenGL Programs with ANSI C

(version of July 16, 2009)

These notes explain how to compile programs written in ANSI C with OpenGL and GLUT using the Dev-C++ compiler.

Bloodshed Dev-C++ is a free C++ compiler and development environment for Windows operating systems. Like most C++ compilers, it also can be used to compile ANSI C. By installing the GLUT header and library files, it can be used to write programs that use OpenGL. This is needed to run programs for Edward Angel's textbook, Interactive Computer Graphics 5th edition and possibly other computer graphics texts.

These notes do not explain how to compile OpenGL with C++ . The 6th edition of Angel's book uses C++ which will not work with these notes.

These instructions have been tested on a small variety of Windows 2000 and Windows XP systems. These systems come with the files needed for OpenGL, but not the files needed for GLUT.

Dev-C++ does not work well with Microsoft's Vista. The problem, and a possible fix, is discussed here: http://aresio.blogspot.com/2007/06/vista-and-dev-cpp.html but I have not tested this information.

I. Download Dev-C++ from http://www.bloodshed.net/dev/devcpp.html and install it.


Get Dev-C++ 5.0 beta 9.2 ( (9.0 MB) with Mingw/GCC 3.4.2 Although this is a 'beta' version, it works perfectly fine. Click on SourceForge to go to a list of download sites and pick one. The file will be something like devcpp4.9.9.2_setup.exe. Save this file in a place like C:Temp.

When the download is complete, click on the 'open' button to start the installation process. (Or go to C:Temp andDouble click on devcpp4.9.9.2_setup.exe). You will see a few screens that ask you to pick a language (English) and to agree to the license terms. Choose a 'typical' installation.

Accept the suggested destination for the installation:

Many subdirectories and files are extracted to the destintion:

Answer 'yes' when it asks if you wish to install Dev-cpp for all users. Note: if the installation fails, re-install and try 'no' for this.

A screen says the installation is complete:

Keep the check mark in the box. Click on 'Finish'. A first-time configuration screen appears:

Pick 'English' and 'New Look'. In the next several screens, hit 'Yes' for its suggestions.

Synth1 by Daichi Laboratory (Ichiro Toda) (@KVRAudio Product Listing): Synth1 is a software synthesizer. Functionally it is modelled on the Clavia Nord Lead 2 Red Synth. Features: 2 Oscillators, FM modulation, ring modulation, sync, modulation envelope. 4 types of filters, distortion. 2 LFOs (synchronized with host). Arpeggiator (synchronized with host). Tempo delay (synchronized with host. Synth1 is a free analog vst with 2 Oscillators FM modulation ring modulation sync,modulation envelop 4 types of filters distortion 2LFO. Soft synth vst.

Eventually you are done. Click 'OK'.

II. DEV-C++ starts up. Try out the installation with a simple C program.


The program starts up automatically.

Click File/New/Project. Pick a name for the project (such as 'myProject'). Click 'C Project'. Click on 'Empty Project'. Click 'OK'.

In 'Create New Project', click 'save' (later on you will probably want to create separate subdirectories for your various projects.).

Click 'File/New/Source File' and in 'Add source file to current project' click 'Yes'. You now get a screen where you can edit the source file.

Type in a simple C program, as below. Now click 'File/Save As' and save the file as 'hello.c' (or other name.) Important: be sure that the file extension is .c. With any other extension (such as the suggested .cpp) you will have problems compiling.

Now click 'Execute/Compile and Run'

The program will (hopefully) compile, run, and write its output to a DOS window. If you have the system('pause') statement in your program, the output will stay in the window until you hit a key. Another way to run the program (after it has been compiled) is to start a DOS window outside of the Dev-Cpp system, then navigate to the subdirectory that holds your project, and type hello.exe.

At this point, the compiler and development environment has been installed. You should find Dev-C++ listed under 'Programs' on the 'Start' menu and will now be able to write, compile, and run C (and C++) programs. You will have include files, libraries, and dll's for OpenGL (and all other standard packages) but not GLUT. GLUT manages the windows and other user interface components needed for OpenGL programming, and needs to be separately installed.

If you do not need GLUT , you can quit now.

III. Download and install GLUT

To run OpenGL with GLUT (which is what the programs in Angel's book use), you need to get three files and place each file in its proper directory. All the files you need (and more) are contained in one zip file.


Download GLUT files from http://chortle.ccsu.edu/Bloodshed/glutming.zip Download the file glutming.zip Save the zip file in some convenient location (perhaps C:temp).

Double click on glutming.zip (or otherwise unzip it). You will see the files that are in the zip archive. (Your un-zipping program will probably be diferent than the one shown here, but should work about the same.)

Click on 'Extract' to extract all the subdirectories and files. Pick some convenient directory to extract them to (perhaps C:tempglutming). You only need three files, but extract all of them anyway.

Only three of the files in the various subdirectories are needed. Each of the three files should be put in a subdirectory with other files of its type. Use Explorer to move the files to where they are needed.

Note: If you only see some of these files listed in Explorer, click on 'View/Options/View' and then select the radio button 'Show all Files'.

glut.h -- copy this file to C:Dev-CppincludeGL

Copy from your 'unzipped' subdirectories (wherever they are):

To here:

libglut32.a -- copy this file from your unzipped directories to C:Dev-Cpplib

There may be a newer version of this file there, already. Replace that version with the one you unzipped (if you keep the newer version your programs will not link correctly.)

Copy from your 'unzipped' subdirectories:

To here:

glut32.dll -- move this file to C:WINNTSystem32, or similar location.

The location for this file depends on your operating system. The directory where it goes is the directory that holds the dynamic load libraries (*.dll). An easy way to find where it should go is to look for glu32.dll (use 'Search' from the start menu).

The directory to use should also have the files glu32.dll and opengl32.dll. These should have come with your operating system.

IV. Test Dev-cpp with GLUT

The essential step in compiling and running a C program that contains OpenGL and GLUT functions is to tell the linker where the libraries are. This is done by clicking Project/Project Options/Parameters/Add Library or Options and then navigating to the libraries you need to include: libopengl32.a, libglu32.a, and libglut32.a. The libraries should be added in that order.


a. Create a subdirectory for a project. Do this first, before you start Dev-Cpp. Create a new subdirectory with 'Explorer' by clicking 'File/New/Folder'.

For example, create a folder C:GLproject.

b. Start Dev-cpp:

c. Start a new project by clicking File/New/Project. In the panel that pops up, name the project something like 'rectangle', click on 'empty project' and 'C': Click OK.

Note: For compiling with OpenGL you must create a project. You need to have a project (not just a single C file) in order to link in the OpenGL libraries.

d. In the next panel, navigate to your folder C:GLproject, and click 'Save'.

e. In Dev-C++, click 'File/New/Source File' and then in the next panel 'Add to Project' click 'yes'. Click 'File/Save As' and then give the file a name. Navigate to your project subdirectory to save the file in it. Name the file something like 'rectangle.c'

Be sure that the file names ends with '.c' anything else will cause big problems.

f. Click and drag your mouse over the following program so that it is highlighted, then click 'Edit/Copy' from the browser's menu bar.

g. Now click in the editing window of Dev-cpp and then click 'Edit/Paste' in its menu bar. The program will appear in the editing window.

h. Click 'File/Save'. The file in your project directory should now contain an OpenGL program.

Dev C++ Source File Not Compiled Error Fix

i. Tell Dev-cpp what libraries need to be linked. Click 'Project/Project Options'.

j. Now click 'Parameters'. Click the 'Add Library or Object' button and navigate to the libraries that should be added, found under C:Dev-cpplib

Dev C++ Source File Not Compiled Error

  • ./lib/libopengl32.a
  • ./lib/libglu32.a
  • ./lib/libglut32.a

C++ Source File Extension

Add them in that order (only). Notice that the slashes will appear in Unix style '/' rather than DOS-style '.

When you are done adding the three libaries, you should see:

The exact pattern of '././.' you see depends on how deep in the directory structure your source file lies.

Click 'OK'.

k. Click 'Execute/Compile and Run'. The program should compile, link, and run:

Dev C++ Source Code

If things don't work (very common) click on the 'Compile Log' tab for some confusing error messages. If you see something like the following, it means that you made a mistake in adding the libraries to the project:

Try to fix the list of libraries, or perhaps start over from scratch.

You now are finished, or have given up.
